I want to purchase my second property within 4-6 months of moving into my multifamily house hack, but looking for a guidance on the strategy to do so.

A 3/2 in CA is a bargain for $300K while in our markets, $300K would get you a move in ready 4/2 on the water. 

If you have a buyer's agent, you should have already signed a buyer's representation agreement and that fee/commission is disclosed in that document so you should very well know what that charge will be.If you were the seller and going to owner finance the property, what would you want to see from the buyer that tells you that they will be able to pay the mortgage moving forward. 

Is Spokane a good place to start house hacking, or would Tucson be a better move?

Quote from @Larissa Leeper: I want to make a move for my first rental.

This move, representing a $900 million investment and the creation of 4,000 new jobs by 2035, positions Columbus, Ohio, at the forefront of technological and economic growth.

You may want to find a good agent in the southern NH area as I'm hearing that market is prime for investment with people moving up from MA, but your other markets might be just as solid.Also, since you're already an agent, it's pretty easy to get your reciprocal license for NH or RI.

Well, there are multiple moving pieces.

But, as my wife and I have done this over the past 5 years, we have found it moves less and less each time, and that we are essentially living the life we envisioned 5 years ago when we started this process. 

This would be our first full rehab and first time using creative financing so I want to make sure I'm underwriting it correctly before we make any moves!
